What is the difference between environmentally friendly wire and cable and ordinary wire?


Environmentally friendly wires and cables are different from ordinary wires and cables. They are not only different in material and process, but also have a world of difference in performance and quality standards from ordinary wires and cables.

1. Flame retardant and fire resistance: When an electrical fire occurs in an environmentally friendly wire and cable, the wire and cable are not easy to burn, and at the same time, it can ensure the normal operation of the circuit system for a certain period of time in the case of continuous combustion, and can reduce the spread of the flame after the wire and cable are burned, and Its production is in full compliance with national fire protection standards.

2. The insulation materials and sheath materials used in environmentally friendly wires and cables ensure the performance of wires and cables while ensuring stable electrical performance and physical and mechanical functions, and avoid the "secondary pollution" formed after the waste wires and cables are incinerated. Therefore, Known as green environmental protection wire and cable.

3. The wire and cable itself has low toxicity: the insulation and outer sheath of the environmentally friendly wire and cable are low-smoke and halogen-free, and do not contain heavy metals such as lead and cadmium that are harmful to the human body. Belongs to low-smoke halogen-free cables. There is a certain guarantee for physical health in daily use.

4. Wires and cables will not decompose corrosive gas: the environmentally friendly wires and cables are made of new special materials, which will not produce a variety of toxic gases due to high temperature and other reasons during use, and cause less harm to equipment and instruments. The environmental protection characteristics of environmental protection wire and cable.

5. Environmentally friendly wires and cables have high mechanical strength: Environmentally friendly cables are made of environmentally friendly materials, which have higher mechanical strength than traditional cables and are not easy to crack. In use, the service life of wires and cables is greatly improved, and the cost of replacement is reduced.

What are the main characteristics of environmentally friendly wire and cable?


 Traditional flame-retardant cables are insulated with polyvinyl chloride materials, while environmentally friendly wires are made of cross-linked polyethylene insulation materials, which have higher heat resistance, safety and stability.

1. High flame retardancy: The flame retardancy of wires and cables is very important. For cables that fully ensure safety and fire prevention requirements, wires and cables are not easy to burn and catch fire, and can prevent the flame from expanding;

2. No peculiar smell and corrosive smell: It does not contain hydrochloric acid and other toxic gases, and is a new environmentally friendly coated wire and cable material produced without pollution to the environment. It will not produce or emit very little acid gas during use and combustion. , to ensure the safety of personnel and reduce equipment and instrument damage and other environmental protection features;

3. High light transmittance: The smoke generated when the environmentally friendly wire and cable is burned is relatively fine, which has little effect on the work of evacuation and fire fighting.

4. Halogen-free, green insulation, special oxygen barrier material: not only has good electrical and mechanical properties, but also ensures that the product does not contain halogens, preventing the formation of carcinogenic dioxins in the combustion process of traditional PVC wires materials to prevent secondary pollution;

5. Waterproof and anti-ultraviolet performance: Due to the special molecular structure of environmentally friendly wires and cables, the production of green and environmentally friendly materials with ultra-low water absorption is guaranteed. The special UV absorber makes the product have good UV protection performance.
